We discussed this issue at LCA where I encountered these bogus error
messages when I was doing the demo of HS. I consider Selena's patch to
be a bug-fix for beta of 9.0, not a feature. Currently the database
reports a lot of false error messages when running in standby mode, and
once we have 1000's more users using standby mode, we're going to see a
lot of related confusion.
The searching for files it doesn't need also delays standby for 15-45s,
so this is a performance fix as well.
